More orcas have died entangled in fishing gear in Alaska this year than in previous years, which may be linked to a "new behavior" where they feed in front of ascending fishing nets.
Lolita, also known as Tokitae, died before she could be returned to her native waters in the Pacific Northwest.
The orca "slurped in the liver and then the whale shark just fell and descended down, with no movement," James Moskito of Ocean Safaris told Live Science.
Four separate incidents on a beach in Fukui prefecture on July 16 echo a string of attacks in the same region last year that may have been perpetrated by a single Indo-Pacific bottlenose dolphin.
From Pliny the Elder to the Swedish naturalist Carl Linnaeus, historians and naturalists have found many ways to describe these fascinating apex predators.
White Gladis was so hellbent on stopping boats in the Strait of Gibraltar that she engaged in attacks instead of protecting her newborn calf.
The behavior may be "leapfrogging" between orca populations, and it could be in response to human activities such as fishing.
The nine Type D orcas were found on a beach in Chile, with a necropsy of one female showing it was a healthy adult, with no signs of human involvement in its death.
As the crew motored inshore after the encounter, one of the orcas reappeared, chased the boat into the marina and tore off what little fiberglass was left on the two rudders.
